    gvariant-internal.h: fix the include hack
    
    gvariant-internal.h was defining GLIB_COMPILATION so that it could
    include individual headers, but this broke tests/gvariant on windows
    because setting GLIB_COMPILATION changes the definition of GLIB_VAR,
    causing external variables to not be found. Fix this by having it
    define __GLIB_H_INSIDE__ instead.
